Mainstream of the engine was changed to a water-cooled engine from the air-cooled engine. Evolution of the engine of the ordinary was going like this.But Suzuki were prepared with different choices.
“To the oil cooling from the cold air cooling”So alien exactly, but it was a reasonable evolution.
1985, first GSX-R750 is released. It was equipped with an engine that uses oil cooling system of newly developed (Suzuki Advanced Cooling System). And, It has adopted the aluminum frame was rare at the time. Dry weight at 179kg, export specification was demonstrated 100ps.
Improvement is overlaid every year after that, the power-up of more than this is determined to be impossible in the oil cold, with GSX-R1100N of 1992, oil cooling as a GSX-R1100 series celebrates the end.
Conducted a full model change in 1989.(GSX-R1100K) R100 from this model became the specifications direction was significantly different from R750. Handle is a separate type, such as the upright position with the handle can be mounted on top on the bridge, it has been changed to high-speed tourer.
1127cc next up about 7%, output is 143ps is up about 10%, the maximum torque was also up 15% and 11.9kg exhaust amount.
GSX-R1100 is to be released in 1986, one year after it is late.How I almost was equipped with an engine of 1100cc to body size of 750. Dry weight is super lightweight at 197kg.
The advantage of oil-cooled engine is that simple and lightweight compared to water-cooled. The water-cooled, you will need to add the ability to cooling or circulating the cooling water. Many benefits will come out in the oil cold do not need is these.
Time the higher output of the air-cooled engine has reached its limit, Suzuki has decided to develop a 750cc machine of more than 100ps at lightweight. Initially water cooling was examined, but will fall into a dilemma cost is up by weight and the increase absolutely, can be complicated.
It is a way to further leverage the oil that is used in cooling and lubrication where it is was flashed. By cooling by spraying the back side of the piston directly to the oil, and delivers the cooling efficiency unprecedented. Results not comparable to the water cooling was obtained.
